ASSIGNOR r0 smmnns 80 OF SIEMENSSTADT, NEAR BERLIN, A CORPORA- PROCESS OF MAKING ASBESTOS BODIES.

No Drawing. Application filed November 7,

worked in other ways.

Asbestos bodies obtained invention can be used, for example, 1n place of the usual insulating bodies.

The compression of the asbestos may advantageously be done at a temperature in the neighborhood of from 1000 to 1200 C.,

and readily attainable pressures at this temperature will produce plates which are easily according to the I 1925, Serial No. 67,688, and. in Germany October 17, 1924.

workable and possess great mechanical strength.

I claim: 1. A process of producing hard bodies from asbestos which comprises heating the asbestos to a high temperature and while it is in this condition, subjecting it to a sufiiciently high pressure to' increase its density.

2. A process for producinghard bodies from asbestos which comprises heatin the asbestos to a temperature in the neighborhood of its melting point, and before it has cooled, subjecting it'to a pressure sullicient to consolidate it.

In testimony whereof I aifix my signature.

HANS GERDIEN.
